The track, which was accompanied by an animated clip, is set to appear on the soundtrack for Marvel’s upcoming Spider-Man: Into the Spider-Verse film. The motion picture and the official soundtrack, which also features Vince Staples in its trailer, is slated for a Dec. 14 release, when the film opens in theaters nationwide.

Post Malone and Swae Lee’s collaboration doubles as the soundtrack’s first single and marks their first time reuniting since the 2017 Beerbongs & Bentleys cut, “Spoil My Night.”

During the vibrant animated clip, the main character, played by Miles Morales, takes viewers through a day in the life as a regular kid, going on to reveal his secret, at times confusing, identity as Spider-Man. The song follows themes of heartbreak, hardship and perseverance, helping bring the coming-to-age story to life.

“Post and Swae have delivered a song that’s both heroic and emotional, which is exactly what a Spider-Man story needs,” Spring Aspers, Head of Music, Creative Affairs Worldwide for Sony Pictures Entertainment’s Motion Picture Group, shared in a statement. “It’s anthemic, but also heartfelt -- the perfect soundtrack for Miles to discover the Spider-Man inside himself.”
